SINCE I BUILT BOTH THE 2 AND 3 ELEMENT 10 METER BEAMS, I FOUND THEM BOTH TO WORK VERY WELL. THE 3 ELEMENT MENTIONED HERE IS NOT AN EXACT COPY OF MINE, BECAUSE I HAVE A SLIGHTLY LONGER VERSION THAT IS ABOUT 16 FEET LONG'

THIS 3 ELEMENT BEAM USES A BOOM OF 1 1/2 INCHES ROUND OR FLAT TUBING.

BOOM TOTAL LENGTH (SLIGHTLY LONGER THAN ELEMENT SPACING) WOULD BE 13 FEET 9 INCHES.THIS EXTRA LENGTH SHOULD ALLOW FOR THE ELEMENT SADDLES OR ATTACHING BRACKETS TO FIT ON BOOM.

INSTRUCTIONS FOR THE 10 METER GAMMA MATCH CAN BE FOUND IN THE COMPANION 2 ELEMENT10 METER ARTICLE IN THIS SECTION UNDER ANTENNA'S.. GAMMA MATCHES ARE NOT DIFFICULT TO BUILD AND ONCE CONSTRUCTED, ARE FAIRLY EASY TO ADJUST FOR A GOOD SWR.YOU MAY WANT TO BORROW AN MFJ ANTENNA ANALYZER TO MAKE TUNING MORE ACCURATE.I HAVE BUILT 15, 10, 6 AND 2 METER GAMMA MATCHING DEVICES, AND ALL HAVE PERFORMED WELL.GAMMA MATCHES CAN BE FOUND AT ARRL ALSO.

TUBING FOR THIS PROJECT CAN BE FOUND AT TEXAS TOWERS ON THE INTERNET.

THESE BEAMS WILL BE A GREAT INVESTMENT TO WORK DX OR STATE SIDE, GIVING YOUR SIGNAL A BETTER PUNCH COMPARED TO A DIPOLE. THE BEAMS ARE ALSO VERY FLAT IN SWR OVER A MUCH WIDER RANGE THAN A DIPOLE MADE OF WIRE.watch for power linesGOOD LUCK AND BE CAREFUL
